I don’t know, but they’ve asked you to call, and you’ve given it 10 minutes then given up. You’re spending more time seemingly to prove something to VM which, on balance, isn’t all that important.
If your ultimate goal is to get one over on VM about it not following its own procedures, crack on. If your goal is to get your account closed, CASS your current account away (which is dead simple and doesn’t involve you interacting with VM at all), and if VM doesn’t close the savings account automatically, call them.
